Slope intercept is the most prominent form of linear equations. When the line is graphed m is the slope of the line and b is where the line crosses the y axis or the y intercept.
For a review of how this equation is used for graphing look at slope and graphing.
How to find slope intercept form. To be able to use slope intercept form all that you need to be able to do is 1 find the slope of a line and 2 find the y intercept of a line. Y 3 2 x 1 y 3 2 x 1 y 3 2 x 1 y minus 3 equals 2 left parenthesis x minus 1 right parenthesis. X 4 y 7.
2 x plus 3 y equals 5. The slope intercept form of an equation is y mx b which defines a line. X 4y 7 x 4y 7.
Let s dig deeper to learn why this is so. Many students find this useful because of its simplicity. X equals 4 y minus 7.
Y mx b y mx b this is called the slope intercept form because m is the slope and b gives the y intercept. The slope intercept form is probably the most frequently used way to express equation of a line. One can easily describe the characteristics of the straight line even without seeing its graph because the slope and y intercept can easily be identified or read off from.
I think the most useful form of straight line equations is the slope intercept form. Slope intercept form of a line y mx b the slope intercept is the most popular form of a straight line. You can use slope intercept form to solve for x y m and b.
